I agree with batkid - and marc, in spirit - but I think it IS okay to accept recurring monies,
we just have to be prepared to not compromise on any principles - if this hypothetical/non-hypothetical grant/donation-giving entity or entities defund us, that's their prerogative. If they try to influence us, then it's up to refuse their money at that time, or tell them to f off.
In other words, it's on us to keep a grip on our principles, and not let outside forces unduly influence us...we do this through statements of principle, bylaws, consensus-based decision-making, etc.
Money is fucking scary. I really feel that way. But let's see if we are strong enough to control it, rather than the other way around, provided we one day have enough cash to worry about its sauron-like influences
